So if you go to Tapas Revolution they will sell you a 'Barraquito Cannario' it's an 'expresso with condensed milk, lemon peel and Licor 43 topped with foamed milk and cinnamon'. Mrs K rather likes them
So for a laugh I bought a bottle of this mysterious 'Licor 43' off Amazon (twas on offer) fully expecting it to be utterly revolting neat.
Oh no it isn't, it's high alcohol high flavoured nectar and unsurprisingly apparently one of Spain's most popular drinks
